I have a 360 controller i can use.
Good stuff. Also, just a tip - weapon damage is less important than their move set. Each weapon handles differently (or many do), use R1/R2 (or the 360 equivalent), push down/up on the left joystick while pushing R1/R2, etc. Find a weapon that has a move set you like the best and then upgrade it after you reach the first blacksmith.
Also, if you're going to make a DEX build, you can get one of the best swords in the game move set wise very early by killing the merchant near the start of the game. It's a Katana, my favorite breed of weapons in the Souls series.
Speaking of that, don't hit ANY npcs in this game without checking on what happens if you do. They can all be killed, some drop great stuff like that sword, some don't and others will hurt your overall game.
I could go on and on and on when it comes to tips, so I'll stop lol.
